>Description:
	Assigning return value of strlen() to double fails.
	Because of this bug, awk doesn't work correctly.
	And this leads build failure of libedit.

>How-To-Repeat:
	% cat a.c
	#include	<stdio.h>

	main()
	{
		double	u;

		u = strlen("abc");

		printf("u = %g\n", u);
	}
	% cc a.c
	% ./a.out
	u = 1.4822e-323
	%

 awk should be built with -msoft-quad-float.  this is a known bug
 (see doc/HACKS) but it should be already worked around.  from
 src/gnu/usr.bin/gawk/Makefile:


 	.if (${MACHINE_ARCH} == "sparc64")
 	CFLAGS+=        -msoft-quad-float
 	.endif

 Oops, I looked at wrong directory(src/usr.bin/awk).
 But awk(gnu/usr.bin/gawk) still doesn't work correctly, so fail to
 build libedit.
 I'll send another PR.

 sparc64:
 % echo 'abc defg' | awk '{print substr($2, 1,2);}'

 % 

 i386:
 % echo 'abc defg' | awk '{print substr($2, 1,2);}'

 this is exactly the problem the workaround should fix.  is your awk
 properly built?  it sounds not.
